How to programmatically configure Android ActionBar

I am developing an application for Google TV where all navigation will be done using the D-Pad / Keyboard.

In my activity there is an ActionBar and several horizontal lists below it. for example, list A, B and the C . Lists B and C load data based on the selected list item A .. so that they can / cannot load data.

The problem is that when the ActionBar has focus, and I press DOWN D-Pad, the focus is lost and not transferred to List C (or B if C has no data). Y?

To achieve this, I tried to make the ActionBar the next smooth view programmatically as follows

getActionBar().getCustomView().setNextFocusDownId(R.Id.list_C_id);

but does not work.

I also tried to check the layout hierarchy using the Hierarchy Viewer ... but, to be honest, I did not understand what to do with its results.

How can I configure Android ActionBar software control programmatically?

Any help is greatly appreciated.

The XML action is as follows:

All containers of each list / grid to the Top of LinearLayout itself set the android: focusable = "true" directly or according to their own style.

EDIT: An example application that describes exactly my spp screen can be downloaded from here.

In the first list indicate . You can find it by id allPackagesList in the main.xml file. I forgot to insert it. excuse me

Problems in this app:

  • Focus does not fall into the list / grid from the ActionBar.
  • ActionBar D-Pad "LEFT" "RIGHT"
+5
1

, ? android: focusable = "true" .
